Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a hemostatic forceps. Background Art

[0002] In order to fully expose the surgical field during surgery, it is necessary to ligate the blood vessels around the target tissue to stop bleeding. Hemostasis technology has become one of the core basic surgical operation techniques. Surgical operations on any part of the human body almost without exception involve bleeding and hemostasis, and hemostatic forceps and ligature clips are generally used to close and stop bleeding.

[0003] During surgical operations, doctors use hemostatic forceps to ligate blood vessels around target tissues. Doctors often first place the blood vessels to be clamped in a V-shaped jaw formed by two clamp arms, in which a V-shaped ligation clamp is pre-placed. The two clamp arms are then closed to allow the V-shaped ligation clamp to close the blood vessels. However, during the clamping process, the existing hemostatic forceps clamp the V-shaped ligation clip contained therein by completely closing the V-shaped jaws. Since the shape and size of the V-shaped jaws formed by the two clamp arms are fixed, the shape and size of the V-shaped jaws after being fully closed are also fixed. Therefore, the clamping force applied to one type of V-shaped ligation clip by the V-shaped jaws when fully closed is fixed. The V-shaped jaws with fixed shape and size and the V-shaped ligation clip of fixed type can only be used to clamp blood vessels of corresponding diameter types. The clamping force applied to the fixed type of V-shaped ligation clip by the V-shaped jaws with fixed shape and size when fully closed cannot be adjusted according to the different diameters of the blood vessels to be clamped. That is, the V-shaped jaws with fixed shape and size and the V-shaped ligation clip of fixed type cannot meet the requirements of clamping blood vessels of different thicknesses.

[0004] There is a hemostatic forceps, such as Figure 1 As shown, the hemostatic forceps include a belt bin structure, a belt feeding structure, a firing structure, a clamp arm and a sleeve; the belt bin structure includes at least one strip tourniquet and a belt bin for accommodating at least one strip tourniquet, and at least one tourniquet is sequentially arranged in the far and near directions and stored inside the belt bin; the belt bin structure is fixedly accommodated in the sleeve; the proximal end of the clamp arm is fixedly installed in the sleeve, and the distal end of the clamp arm has a hook portion, which extends out of the sleeve, and a belt feeding groove is provided on the clamp arm, and the proximal end of the belt feeding groove is located in the sleeve and connected with the inner space of the belt bin to form a belt feeding channel, and the distal end of the belt feeding groove is located on the inner side of the hook portion and is bent along the shape of the hook portion; the distal end of the belt feeding structure is inserted into the sleeve, and the belt feeding structure cooperates with the tourniquet; the firing structure is penetrated into the sleeve, and the firing structure cooperates with the hook portion.

[0005] During the process of clamping the blood vessel with the hemostatic forceps, the blood vessel to be clamped is located in the jaws formed by the curved hook portion, the tourniquet located at the farthest end of the belt feeding channel is the tourniquet to be inserted into the clamp, the belt feeding structure moves farthest, and pushes all the tourniquets in the belt feeding channel to move farthest, when the belt feeding structure is located at the far end position of the belt feeding structure, the far end of the tourniquet to be inserted into the clamp is bent into an annular portion along the belt feeding groove to surround the blood vessel to be clamped, and the far end of the tourniquet to be inserted into the clamp extends out of the belt feeding groove; the firing structure moves farthest, and closes the annular portion of the tourniquet to be inserted into the clamp, thereby clamping the blood vessel to be clamped.

[0006] The above-mentioned hemostatic forceps can realize the control of the firing structure stroke, the control of the firing structure and the clamping force applied to the blood vessel to be clamped by the hook part of the clamp arm, so that the one hemostatic forceps can be used to clamp blood vessels of different thicknesses, and there is no need to frequently replace different types of hemostatic forceps according to the different diameters of the blood vessels to be clamped. Specifically, the one hemostatic forceps can be used to clamp blood vessels of different thicknesses, as explained below: the blood vessel wall of the thick blood vessel is thicker, and the blood vessel wall of the thin blood vessel is thinner. In order to stably clamp the blood vessel with the hemostatic forceps, the distance between the firing structure and the hook part should be less than or equal to the thickness of the two blood vessel walls of the blood vessel to be clamped, but the distance between the firing structure and the hook part cannot be too less than the thickness of the two blood vessel walls of the blood vessel to be clamped, which will cause necrosis of the blood vessel wall tissue; the above-mentioned hemostatic forceps can adjust the distance between the firing structure and the hook part to be appropriately less than or equal to the thickness of the two blood vessel walls of the blood vessel to be clamped by controlling the firing structure stroke, that is, it can control the firing structure and the clamping force applied to the blood vessel to be clamped by the hook part of the clamp arm, and thus can be used to clamp blood vessels of different thicknesses.

[0007] However, the working process of the firing structure to close the blood vessel to be clamped occurs inside the closed shell of the hemostatic forceps and is located inside the human body. The doctor cannot accurately know the working process of the firing structure from the outside, and it is difficult to control the clamping force applied to the blood vessel to be clamped by adjusting the stroke of the firing structure and the hook part of the forceps arm to clamp blood vessels of different thicknesses. Summary of the invention

[0016] The adapter includes a housing and an indicating structure. The distal end of the housing forms a first insertion channel, and a driving shaft is inserted into the first insertion channel. The proximal end of the tube body is plugged into the first insertion channel, and the driving shaft is connected to the proximal end of the first actuator.

[0017] The indication structure includes a motion indicating needle accommodated in a shell and an observation position formed on the shell and arranged corresponding to the motion indicating needle; the motion indicating needle is arranged in linkage with the driving shaft, and during the process of the motion indicating needle following the movement of the driving shaft, the indicating end of the motion indicating needle is always located in the observation position; at least two firing completion indication scales of blood vessel types with different diameters arranged from near to far are marked on the observation position or on the shell near the motion trajectory of the indicating end of the motion indicating needle.

The control unit determines the current stroke information of the firing structure based on the displacement data and a preset firing structure stroke trajectory, and outputs the determination result through the prompt unit.

[0027] (III) Beneficial effects

[0028] The beneficial effects of the present invention are:

[0029] A motion indicator needle that is linked to the drive shaft is arranged to cooperate with an observation position arranged on the shell, and at least two firing completion indication scales of different diameter blood vessel types arranged from near to far are marked on the observation position or on the shell near the motion trajectory of the indicating end of the motion indicator needle. When the indicating end of the motion indicator needle moves to the firing completion indication scale of a blood vessel type with a certain diameter, the drive shaft drives the magazine assembly to fire the blood vessel of that diameter, thereby enabling the user to obtain the working progress information inside the hemostat based on the movement of the motion pointer observed through the observation position outside the hemostat, thereby guiding the user to use the hemostat to clamp blood vessels of different thicknesses.

[0060] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Among them, the "near" mentioned herein refers to the side close to the operator, and the "far" refers to the side close to the patient. The directional terms such as "upper", "lower", "front", "back", "left", "right" mentioned herein are in the order of Fig.11 The orientation is a reference, where the direction from near to far is also the direction from back to front.

[0061] To further clearly illustrate the hemostatic forceps mentioned in the background technology of the present invention, Figure 1-10 A detailed description is given as an example.

[0062] like Figures 1 to 6 As shown, the hemostatic forceps provided in this example include an adapter 8 and a cartridge assembly 1 .

[0063] The tape bin assembly 1 includes a first actuator (the actuator structure and its working principle have been embodied in the Chinese patent CN201911021573.1, with an application date of October 25, 2019 and a publication date of April 27, 2021. The entire text of the present invention refers to the patent and will not be repeated here), a tape bin structure, a tape feeding structure, a firing structure, a clamp arm 2, and a tube body 11 and a sleeve 12 arranged in sequence from near to far.

[0064] The distal end of the tube body 11 is communicated with the proximal end of the sleeve 12, and the proximal end of the sleeve 12 is fixedly connected to the distal end of the tube body 11. The first actuator is accommodated in the tube body 11.

[0065] The belt bin structure includes at least one strip tourniquet 41 and a belt bin 42 for accommodating at least one strip tourniquet 41. At least one tourniquet 41 is sequentially arranged in the near and far directions and stored inside the belt bin 42. The belt bin structure is accommodated in the sleeve 12, and the belt bin structure is fixedly connected to the sleeve 12. The clamp arm 2 has a straight portion and a hook portion 21 connected sequentially from near to far. The proximal end of the straight portion is fixedly installed in the sleeve 12, and the hook portion 21 extends out of the sleeve 12. A belt feeding groove 22 is formed on the clamp arm 2. The proximal end of the belt feeding groove 22 (i.e., the first end of the belt feeding groove 22) is located in the straight portion, and the distal end of the belt feeding groove 22 (i.e., the second end of the belt feeding groove 22) is located on the inner side of the hook portion 21 (i.e., the side of the hook portion 21 facing the sleeve 12) and is bent along the shape of the hook portion 21. The tape bin bottom plate is placed on the straight portion, the tape feeding groove 22 is located on the far side of the tape bin bottom plate, the proximal bottom surface of the tape feeding groove 22 is coplanar with the top surface of the tape bin bottom plate, and the proximal end of the tape feeding groove is provided with an opening toward the tape bin to communicate with the space inside the tape bin 42; during the tape feeding process, the tape feeding structure pushes the tourniquet to leave the tape bin bottom plate and enter the tape feeding groove 22 from the proximal opening of the tape feeding groove 22.

[0066] The distal end of the belt feeding structure is inserted into the sleeve 12, the belt feeding structure cooperates with the tourniquet 41, the proximal end of the belt feeding structure is inserted into the tube body 11, and the proximal end of the belt feeding structure is connected to the first actuator so that the first actuator drives the belt feeding structure to move in the distal and proximal directions, and is used to push the tourniquet 41 in the belt feeding channel to move distally (when the first actuator drives the belt feeding structure to move distally), and is used to reset the belt feeding structure to the initial state after the tourniquet 41 is pushed (when the first actuator drives the belt feeding structure to move proximally). During the process of clamping the blood vessel, the tourniquet located at the farthest end of the belt bin 42 is the tourniquet 43 to be inserted into the slot, the belt feeding structure moves distally, and all the tourniquets in the push belt bin 42 move distally, wherein the tourniquet 43 to be inserted into the slot is pushed into the belt feeding slot 22, and when the belt feeding structure is located at the distal end position of the belt feeding, the distal end of the tourniquet 43 to be inserted into the slot is bent into a ring-shaped portion along the belt feeding slot 22 (such as Figure 3 and Figure 4 As shown), the distal end of the tourniquet 43 to be inserted into the groove extends beyond the belt feeding groove 22.

[0067] The proximal end of the firing structure is inserted into the tube body 11, and the proximal end of the firing structure is connected to the first actuator, so that after the belt feeding structure completes the belt feeding, the first actuator drives the firing structure to move in the distal direction, so that (when the first actuator drives the firing structure to move distally) the firing structure snaps the ring-shaped portion (such as the ring-shaped portion) of the tourniquet 43 to be inserted into the groove. Figure 5 and Figure 6 As shown in FIG. 1 , and used to reset the firing structure after snapping the tourniquet 41 to the initial state (when the first actuating member drives the firing structure to move proximally). The ring shape referred to in the present invention refers to any surrounding shape that can form a hollow, not just a circle shape.

[0068] In the tape bin assembly 1 thus configured, in the initial state, the tape feeding structure is located at the tape feeding initial position, and the firing structure is located at the firing initial position. The hook-shaped portion 21 of the clamp arm 2 in the tape bin assembly 1 is used to hook the blood vessel to be clamped, and then the first actuator drives the tape feeding structure to move far, pushing all the tourniquets 41 in the tape bin to move far, wherein the tourniquet 43 to be inserted into the groove is pushed into the tape feeding groove 22, and the tape feeding structure is located at the tape feeding termination position, and the distal end of the tourniquet 43 to be inserted into the groove is bent along the shape of the tape feeding groove 22 to a ring-shaped portion, and the blood vessel to be clamped is located within the ring-shaped portion (i.e., the ring-shaped portion surrounds the blood vessel to be clamped). Afterwards, the first actuator drives the firing structure to move far to the firing termination position, causing the distal end of the firing structure to snap the ring-shaped portion of the tourniquet 43 to be inserted into the groove, so that the tourniquet 43 to be inserted into the groove clamps the blood vessel. Finally, the first actuator drives the firing structure and the belt feeding structure to reset to the initial state. During the reset process, the first actuator first drives the firing structure to move from the firing end position to the firing initial position, and then the first actuator drives the belt feeding structure to move from the belt feeding end position to the belt feeding initial position, so as to separate the clamped blood vessel from the jaws formed by the hook-shaped portion 21.

[0069] The adapter 8 includes a first insertion channel 81 and a driving shaft 82 passing through the first insertion channel 81 .

[0070] The proximal end of the tube body 11 is inserted into the first insertion channel 81, the proximal end of the tube body 11 is connected to the first insertion channel 81, the drive shaft 82 is located on the proximal side of the first actuator, and the distal end of the drive shaft 82 is connected to the proximal end of the first actuator for driving the first actuator. In this example, the proximal end of the tube body 11 and the first insertion channel 81 are relatively immobile in the proximal and distal directions.

[0071] Preferably, the belt bin 42 includes a belt bin top plate (not shown in the figure) located at the far end of the belt bin 42, and the two sides of the belt bin top plate are respectively connected to the two side walls of the belt bin 42; an elastic pressure plate is provided on the belt bin top plate, which is tilted along the belt feeding direction and toward the belt feeding groove 22; during the belt feeding process, when the tourniquet 43 to be entered into the groove enters the belt feeding groove 22, the tourniquet 43 to be entered into the groove is pressed by the elastic pressure plate.

[0072] Preferably, if Figure 7 and Figure 8 As shown, a first mounting groove 26 is provided on the left side surface at the far end of the tape feeding groove 22 along the tape feeding groove 22, and a second mounting groove 27 is provided on the right side surface of the tape feeding groove 22 at a position corresponding to the first mounting groove 26; a first clamping strip 28 is installed in the first mounting groove 26, a first side portion of the first clamping strip 28 extends into the first mounting groove 26, a second side portion of the first clamping strip 28 extends out of the first mounting groove 26, and the first side portion of the first clamping strip 28 is connected to the bottom of the first mounting groove 26 by a first reset member 30; a second clamping strip 29 is installed in the second mounting groove 27, a first side portion of the second clamping strip 29 extends into the second mounting groove 27, a second side portion of the second clamping strip 29 extends out of the second mounting groove 27, and the first side portion of the second clamping strip 29 is connected to the bottom of the second mounting groove 27 by a second reset member 31; a curved channel for the advancement of the tourniquet 41 is formed between the first clamping strip 28 and the bottom of the tape feeding groove 22, and between the second clamping strip 29 and the bottom of the tape feeding groove 22. The first restoring member 30 and the second restoring member 31 can be tension springs, compression springs, rubber members, etc.

[0073] Such arrangement can prevent the tourniquet 43 to be inserted into the groove from being separated from the belt feeding groove 22 during the belt feeding process, and the belt feeding is stable. At the same time, it is beneficial for the distal end of the tourniquet 43 to be stably bent along the belt feeding groove 22 to the ring-shaped portion. In addition, in the process of the firing structure's distal end snapping the circular portion of the tourniquet 43 to be inserted into the groove, the firing structure applies force to snap the tourniquet 43 to be inserted into the groove to act on the first clamping strip 28 and the second clamping strip 29, and the first reset member 30 and the second reset member 31 yield, prompting the first clamping strip 28 and the second clamping strip 29 to retract into the first mounting groove 26 and the second mounting groove 27 respectively. At this time, since the overall thickness of the clamped tourniquet 41 and the clamped blood vessel (i.e., the sum of the thickness of the two layers of tourniquet 41 and the thickness of the two layers of the blood vessel wall to be clamped) is relatively large, the two side portions of the clamping whole will respectively press against the first clamping strip 28 and the second clamping strip 29, restricting the first clamping strip 28 from extending from the first mounting groove 26, and restricting the second clamping strip 29 from extending from the second mounting groove 27, so that after the firing structure is reset, the clamping whole is easy to be released from the tape feeding groove 22.

[0074] Further preferably, the second side portion of the first clamping strip 28 has a first guide surface 32 extending from the outside of the tape feeding slot 22 to the inside of the tape feeding slot 22, the first guide surface 32 is arranged toward the outside of the tape feeding slot 22, and the first guide surface 32 extends from the first end of the first clamping strip 28 to the second end of the first clamping strip 28, and the second side portion of the second clamping strip 29 has a second guide surface 33 extending from the outside of the tape feeding slot 22 to the inside of the tape feeding slot 22, the second guide surface 33 is arranged toward the outside of the tape feeding slot 22, and the second guide surface 33 extends from the first end of the second clamping strip 29 to the second end of the second clamping strip 29. In this way, through the first guide surface 32 and the second guide surface 33, it is convenient for the firing structure to apply force to snap the tourniquet 43 to be inserted into the slot to act on the first clamping strip 28 and the second clamping strip 29, so that the first reset member 30 and the second reset member 31 yield.

[0075] Further preferably, the first end of the curved channel is located at the proximal end of the belt feeding groove 22, and the second end of the curved channel is located at the top of the hook-shaped portion 21. When the tourniquet 43 to be inserted into the groove is being fed along the belt feeding groove 22, the distal end of the tourniquet 43 to be inserted into the groove enters the belt feeding channel, and the proximal end of the tourniquet 43 to be inserted into the groove is compressed by the elastic compression sheet 49. In this way, the belt feeding stability of the tourniquet 43 to be inserted into the groove is further improved in the belt feeding groove 22, and the mechanism is prevented from being stuck.

[0076] Preferably, in this example, the firing structure, the belt feeding structure, the belt storage structure and the clamp arm 2 are arranged in sequence from top to bottom in the sleeve 12. Further preferably, when the belt feeding structure is at the belt feeding distal end position, the tourniquet 43 to be inserted into the groove is bent into a ring-shaped portion along the belt feeding groove 22 as a whole.

[0077] Preferably, if Figure 2As shown, the bottom surface distal end of the tape feeding groove 22 includes an arc surface 24 and a bending surface 25 connected in sequence, the arc surface 24 extends from the bottom of the hook portion 21 to the top of the hook portion 21, the direction of the arc surface 24 is consistent with the direction of the hook portion 21, the bending surface 25 is located at the top of the hook portion 21, the direction of the bending surface 25 deviates from the direction of the hook portion 21 and is downward, and the tangent direction of the free end of the bending surface 25 is close to the bottom of the hook portion 21. In this way, by providing the arc surface 24, it is beneficial for the tourniquet 41 to bend along the direction of the hook portion 21, and by providing the bending surface 25, it is beneficial for the tourniquet 41 to bend downward to form a ring-shaped portion to wrap the blood vessel to be clamped. Further preferably, the arc surface 24 is a circular arc surface.

[0078] Further preferably, the arc surface 24 has a first connection position for connecting to the bending surface 25, and the bending surface 25 has a second connection position for connecting to the arc surface 24, and the angle formed by the tangent direction of the first connection position in the far-near direction and the tangent direction of the second connection position in the far-near direction is greater than 100°.

[0079] Preferably, if Figure 3 As shown, the distal end of the firing structure has a snapping head 51 for snapping the loop portion of the tourniquet 41, and the distal side of the snapping head 51 has a snapping surface 52 adapted to the setting of the arc surface 24; during the firing process, the snapping head 51 moves far away into the hook groove of the hook portion 21. Further preferably, a groove (not shown in the figure) is provided at the bottom of the snapping head 51 for the distal end of the tape feeding piece 7 to pass through.

[0080] The tape feeding structure includes a transmission member 6 and a tape feeding piece 7. Figure 1 As shown, the transmission member 6 is located inside the belt bin 42 and is placed adjacent to the final tourniquet 41, that is, the distal end of the transmission member 6 can abut against the tail of the final tourniquet 41 when necessary to push the final tourniquet 41, thereby pushing the remaining tourniquets 41 except the tourniquet 43 to be inserted into the groove to move distally.

[0081] The transmission member 6 includes a first transmission structure that can form a one-way transmission connection relationship with the tape feeder 7. The first transmission structure can be Fig.10 The elastic push piece 61 formed on the transmission member 6 is shown as an example. In the natural state (i.e. when the transmission member 6 is taken out from the tape compartment 42), the elastic push piece 61 is preferably a preformed slender cantilever structure, which tilts from the far end of the transmission member 6 to the near end of the transmission member 6 and above the transmission member 6, forming an angle with the transmission member 6, and at the same time, the free end of the cantilever structure forms a first tilted end 62 that abuts against the tape feed piece 7. At the same time, a second transmission structure that forms a one-way transmission connection relationship with the elastic push piece 61, especially with the first tilted end 62 of the elastic push piece 61, is formed on the tape feed piece 7. The second transmission structure is Figure 2The several one-way push grooves 71 exemplarily shown and provided at the bottom of the tape feeding piece 7 are used to engage with the elastic push piece 61 provided on the transmission member 6 .

[0082] Preferably, the proximal wall of the one-way push groove 71 is a push wall 72, and the distal wall of the one-way push groove 71 is an inclined wall 73 inclined toward the distal end; the elastic push member 61 is located in one of the multiple one-way push grooves 71 in a natural state, and when the tape feeding plate 7 moves toward the distal end of the tape magazine 42, the proximal wall of the one-way push groove 71 and the elastic push member 61 form a same-direction push transmission, that is, the first cocked end 62 of the elastic push member 61 is engaged in one of the one-way push grooves 71 and abuts against the proximal wall of the engaged one-way push groove 71. Then, when the tape feeding plate 7 moves toward the distal end, due to the abutment of the cocked end with the proximal wall, the transmission member 6 moves synchronously toward the distal end. After the tape feeding piece 7 completes feeding the tape into the bending part of the tape feeding groove 22, when it moves to the proximal end of the tape bin 42 to reset, the first raised end 62 of the elastic push piece 61 disengages from the state of abutting against the proximal wall, and slides along the distal wall of the one-way push groove 71 until the two disengage and enter the next one-way push groove 71.

[0083] The transmission member 6 also includes a first stop structure formed thereon for preventing the transmission member 6 from moving toward the proximal end of the belt compartment 42. The first stop structure may be an elastic stop member 63, such as Fig. 9 As shown in the exemplary embodiment, the elastic stopper 63 is a stopper spring sheet provided on the transmission member 6, and the stopper spring sheet is preferably tilted toward at least one side of the top of the tape compartment 42 in the middle of the transmission member 6 in the left-right direction. Preferably, the elastic stopper 63 is integrally protruded from the upper surface of the transmission member 6, and its height can exceed the top of the tape compartment 42 to ensure that the second tilted end 64 of the elastic stopper 63 tilted toward at least one side of the top of the tape compartment 42 can accurately engage with at least one side of the top of the tape compartment 42, so that when the tape feeding piece 7 moves toward the proximal end of the tape compartment 42 to reset, the transmission member 6 does not move toward the proximal end.

[0084] In this example, the elastic stopper 63 is preferably as shown in FIG. Fig. 9 As shown, it includes a horizontal portion 65 and an inclined portion 66 located in the same horizontal plane and arranged at an angle to each other. The horizontal portion 65 is located on the far side of the inclined portion 66, and the horizontal portion 65 is parallel to the axis of the belt compartment 42, extends in the far and near direction, and is located in the middle of the transmission member 6 in the left and right direction. The horizontal portion 65 is connected to the fixed end 67 of the transmission member 6, which is the distal end of the elastic stop member 63. The other end of the horizontal portion 65 is connected to one end of the inclined portion 66. The inclined portion 66 is extended / tilted from the connected end toward at least one side of the top of the belt compartment 42 to form a second tilted end 64, that is, the inclined portion 66 is extended / tilted from the connected end to the left and / or right. When in use, the angle between the horizontal portion 65 and the inclined portion 66 is formed to allow the transmission member 6 to move distally in the belt compartment 42. The fixed end 67 is as shown in FIG. Fig.10As shown by way of example, it is generally a "T"-shaped structure.

[0085] Preferably, at the top of one of the side walls of the tape bin 42, a side top wall 44 substantially parallel to the tape bin bottom plate extends perpendicular to the side wall, and the side top wall 44 and the elastic stopper 63 of the transmission member 6 are substantially located at the same horizontal plane. More preferably, the height of the elastic stopper 63 can be slightly higher than the side top wall 44 to ensure that the elastic stopper 63 is engaged with the second stopper structure provided on the side top wall 44 to prevent the transmission member 6 from undesirably moving toward the proximal end of the tape bin 42. The second stopper structure provided on the side top wall 44 of the tape bin 42 can have different structures. In this example, one of the second stopper structures is a one-way stopper groove 45; Fig.10 As shown, the open notch of the one-way stop groove 45 is horizontally oriented toward the middle part of the left-right direction of the top of the belt compartment 42, so that the elastic stopper 63 integrally protruding from the transmission member 6 is tilted from the middle of the transmission member 6 horizontally toward the top wall 44 of the belt compartment 42 and enters the one-way stop groove 45. Among them, the proximal wall of the one-way stop groove 45 is a stop wall 46, and the distal wall is a slide-out wall 47 suitable for the elastic stopper 63 to slide in the distal direction to enter the next one-way stop groove 45. The elastic stop member 63 is located in a one-way stop groove 45 in a natural state. When the tape feeding piece 7 moves toward the far end of the tape magazine 42, due to the one-way transmission connection between the transmission member 6 and the tape feeding piece 7, the transmission member 6 will move toward the far end with the tape feeding piece 7. At this time, the sliding wall 47 forms a bias on the second tilted end 64 of the elastic stop member 63. As the transmission member 6 moves further toward the far end, the second tilted end 64 will slide out of the one-way stop groove 45 where it was originally located, and enter the next one-way stop groove 45 toward the far end and engage with it; when the tape feeding piece 7 moves toward the proximal end of the tape magazine 42, the stop wall 46 of the one-way stop groove 45 and the second tilted end 64 of the elastic stop member 63 form an abutment stop to prevent the transmission member 6 from sliding toward the proximal end of the tape magazine 42.

[0086] In this example, the tourniquet 43 to be inserted into the slot is pushed by the head of the tape feeding piece. To facilitate the head of the tape feeding piece to push the tourniquet 43 to be inserted into the slot, preferably, a notch for accommodating the head of the tape feeding piece is provided at the proximal end and / or the distal end of the tourniquet. In this way, a space for accommodating the head of the tape feeding piece is formed between adjacent tourniquets through the notch, so that the head of the tape feeding piece can push the tourniquet 43 to be inserted into the slot.

[0087] During the resetting process of the belt feeding structure, the belt feeding structure moves toward the proximal end of the belt magazine. Due to the obstruction of the adjacent tourniquet on the proximal side of the tourniquet 43 to be inserted into the groove and the elasticity of the head of the belt feeding piece, the head of the belt feeding piece will pass over the adjacent tourniquet on its proximal side and move to the recess 48 to stop, preparing for the next belt feeding and firing.

[0088] Example 1

[0089] like Fig.11 As shown, based on the hemostatic forceps provided in the above specific implementation mode, in the hemostatic forceps provided in this embodiment, the adapter 8 also includes a housing 83, the distal end of the housing 83 forms a first insertion channel 81, and the drive shaft 82 is inserted into the first insertion channel 81 (that is, the proximal end of the drive shaft 82 is accommodated in the housing 83, and the distal end of the drive shaft 82 is located in the first insertion channel 81). The proximal end of the tube body 11 can be selectively inserted into the first insertion channel 81, the drive shaft 82 is connected to the proximal end of the first actuator, and the drive shaft 82 performs linear motion along its axial direction to drive the first actuator.

[0090] It can be seen that the working process of the hemostatic forceps mainly includes clamp feeding and firing, and the clamp feeding work and firing work are implemented in sequence, and both are realized by the driving shaft 82 that performs linear motion to drive the first actuator. Based on this, in order to solve the problems existing in the background technology, the present application provides a hemostatic forceps with the following structure.

[0091] like Figures 11 to 14 As shown, the adapter 8 also includes an indicating structure for indicating the movement position of the drive shaft 82; the indicating structure includes a movement indicating needle 84 accommodated in the shell 83 and an observation position formed on the shell 83 and arranged corresponding to the movement indicating needle 84, through which the interior of the shell 83 can be observed from the outside of the shell 83; the movement indicating needle 84 is arranged in linkage with the drive shaft 82, and in the process of the movement indicating needle 84 following the movement of the drive shaft 82, the indicating end of the movement indicating needle 84 is always facing the observing position; at the observation position or on the shell 83 close to the movement trajectory of the indicating end of the movement indicating needle 84, there are marked with firing completion indicating scales of at least two different diameter blood vessel types arranged from near to far.

[0092] Thus, when the indicating end of the motion indicator needle 84 moves to the firing completion indicating scale of a blood vessel type with a certain diameter, the driving shaft 82 drives the cartridge assembly 1 to fire the blood vessel with the diameter. This enables the user to obtain the working progress information inside the hemostat according to the movement of the motion indicator observed through the observation position outside the hemostat, thereby guiding the user to use the hemostat to clamp blood vessels of different thicknesses.

[0093] Preferably, in this embodiment, the observation position is a transparent cover 85 provided on the housing 83. Of course, the transparent cover 85 provided on the housing 83 is only preferred as the observation position, and it can be imagined that the observation position is a through hole opened on the housing 83, which can also achieve a similar effect.

[0094] Preferably, the motion indicator needle 84 is fixedly mounted on the drive shaft 82 perpendicular to the axial direction of the drive shaft 82, and the motion indicator needle 84 is located at the proximal end of the drive shaft 82. In this way, the structure is compact and the indicator needle is placed close to the user for easy observation by the user. Of course, placing the motion indicator needle 84 at the proximal end of the drive shaft 82 is only preferred. It can be imagined that placing the motion indicator needle 84 at the middle or distal end of the drive shaft 82 can also achieve a similar effect.

[0095] Further preferably, in this embodiment, the motion indicator needle 84 and the transparent cover 85 are both arranged on the left side of the driving shaft 82. In this way, when the user holds the hemostatic forceps in his right hand, it is convenient for the user to observe the motion of the motion indicator needle 84.

[0096] Further preferably, in this embodiment, the transparent cover 85 is waist-shaped extending in the far and near directions.

[0097] Further preferably, in this embodiment, firing completion indicator scales for different diameter blood vessel types are marked on the transparent cover 85 .

[0098] Further preferably, three firing completion indication scales of different blood vessel types with different diameters are marked on the observation position or on the shell 83 near the motion trajectory of the indicating end of the moving indicating needle 84, and the three firing completion indication scales of different blood vessel types with different diameters are respectively a firing completion indication scale 86 for thick blood vessels, a firing completion indication scale 87 for medium blood vessels, and a firing completion indication scale 88 for thin blood vessels, which are arranged from near to far; wherein, thick blood vessels refer to blood vessels with a diameter of 5 to 7 mm, medium blood vessels refer to blood vessels with a diameter of 3 to 5 mm, and thin blood vessels refer to blood vessels with a diameter of 1 to 3 mm.

[0099] Of course, at the observation position or the position on the housing 83 close to the motion track of the indicating end of the moving indicating needle 84, there are two firing completion indicating scales of different diameter blood vessels, which are respectively the firing completion indicating scale 86 of the thick blood vessel and the firing completion indicating scale 88 of the thin blood vessel arranged from near to far; wherein, the thick blood vessel refers to the blood vessel with a diameter of 4 to 7 mm, and the thin blood vessel refers to the blood vessel with a diameter of 1 to 4 mm. A similar effect can also be achieved.

[0100] Further preferably, the lengths of the firing completion indicator scales of the three different diameter blood vessel types are different, wherein the firing completion indicator scale 86 of the thick blood vessel is the longest, and the firing completion indicator scale 88 of the thin blood vessel is the shortest.

[0101] In order to further clearly distinguish the firing completion indication scales of different diameter blood vessels, in this embodiment, the transparent cover 85 is marked with the position corresponding to each firing completion indication scale with the identification "L", "M" or "S" of the diameter blood vessel type to which the firing completion indication scale belongs, where "L" represents thick blood vessels, "M" represents medium blood vessels, and "S" represents small blood vessels.

[0102] Preferably, if Fig.11 As shown, the hemostatic forceps also includes a drive assembly 91; the adapter 8 also includes a second actuator, a second insertion channel 89 is formed on the shell 83, the power input end of the second actuator is located in the second insertion channel 89, and the power output end of the second actuator is accommodated in the shell 83 and connected to the drive shaft 82, which is used to drive the drive shaft 82; the drive assembly 91 can be selectively inserted into the second insertion channel 89, and the power output end of the drive assembly 91 is connected to the power input end of the second actuator, which is used to drive the second actuator. The adapter 2 configured in this way can select the human drive assembly 91 to be inserted into the second insertion channel 89 in the event of electrical failure during use, and can realize the function of moving the indicator needle 84 while realizing the clamp delivery function and the firing function. That is to say, the hemostatic forceps provided in this embodiment can still display the working progress information of the hemostatic forceps to the user in the event of electrical failure, and guide the user to complete the surgical operation.

[0103] Further preferably, in the present embodiment, a second insertion channel 89 is formed at the bottom of the shell 83, the hemostatic forceps also includes a handle 9, a drive assembly 91 is accommodated in the handle 9, a power output end of the drive assembly 91 extends out of the top end of the handle 9, the top end of the handle 9 can be selectively inserted into the second insertion channel 89, and the power output end of the drive assembly 91 is connected to the power input end of the second actuator.

[0104] Preferably, if Fig.12 As shown, the adapter 8 also includes a control unit, a prompt unit, and a displacement sensor 92 disposed on the drive shaft 82. The displacement sensor 92 and the prompt unit are both connected to the control unit for communication. The displacement sensor 92 collects displacement data of the drive shaft 82. The control unit determines the current stroke information of the firing structure according to the displacement data and the preset firing structure stroke trajectory, and outputs the determination result through the prompt unit. In this way, on the basis of the mechanical structure displaying the internal working process information of the hemostatic clamp, the integrated electrical control displays the internal working process information of the hemostatic clamp, which is more convenient for guiding the user to perform the blood vessel clamping operation.

[0105] Furthermore, the reminder unit may be a display unit or a playback unit, preferably a display unit, specifically a display screen, through which the user can see the working progress information inside the hemostatic forceps during the current clamping operation.

[0106] Specifically, in this embodiment, the display unit is a display screen integrated at the proximal end of the adapter 8 .

The housing 21 has a first transparent cover and a second transparent cover. The indicating end of the first motion indicator needle faces the first transparent cover, and the indicating end of the second motion indicator needle faces the second transparent cover. The movement process of the indicating end of the first motion indicator needle following the drive shaft all occurs in the first transparent cover, and the movement process of the indicating end of the second motion indicator needle following the drive shaft all occurs in the second transparent cover. At least two firing completion indicating scales of different diameter blood vessels arranged from near to far are marked on the first transparent cover and the second transparent cover near the motion track of the indicating end of the motion indicator needle. In this way, it is further convenient for users to observe the movement of the motion indicator needle.

[0110] Preferably, the first movement indicating needle and the first transparent cover are arranged on the left side of the driving shaft, and the second movement indicating needle and the second transparent cover are arranged on the right side of the driving shaft.

In this way, the motion amplitude occurring on the drive shaft 82 for adjusting the firing stroke is amplified by the amplifying structure, so as to be displayed by the motion indicating needle 84, which is convenient for the user to observe.
